Historical fire pits were sometimes built in the floor, in caves, or in the center of a hut or dwelling. Evidence of prehistoric, man-made fires exists on all five inhabited continents. The disadvantage of early indoor fire pits was that they generated hazardous or irritating smoke inside the house.Fire pits grown into raised hearths in buildings, but venting smoke relied on open windows or openings in roofs. The medieval great hall typically needed a centrally located hearth, where a open fire burnt with all the smoke climbing into the vent in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be covered so snow and rain wouldn't enter.
Also throughout the Middle Ages, smoke canopies were invented to stop smoke from spreading through an area and vent it out through a wall or roof. These could be placed against rock walls, instead of taking up the center of the room, and this enabled smaller rooms to be warmed.Chimneys were invented in northern Europe in the 11th or 12th centuries and mostly fixed the issue of fumes, more faithfully venting smoke out. They made it feasible to provide the fireplace a draft, and made it possible to put fireplaces in multiple rooms in buildings handily. They did not come into general use instantly, however, since they were expensive to develop and maintain.In 1678 Prince Rupert, nephew of Charles I, increased the grate of the fireplace, improving the venting and airflow system. The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace that greatly improved the efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting out a longer area at the top. At the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox that was better at drawing the smoke up and out of the building. The shallow design also improved greatly the amount of radiant heat projected into the room. Rumford's design is the foundation for modern fireplaces.
Instead it depended on simple layouts with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was still placed on supplying quality gems. Stone fireplaces at this time have been a symbol of wealth, which to some degree remains the notion today.A fireplace is a structure made from brick, stone or metal made to contain a fire. Fireplaces are used for the relaxing ambiance they create and for heating a room. Modern fireplaces vary in heat efficacy, depending on the plan.Historically they were utilized for heating a home, cooking, and heating water for laundry and domestic uses. A fireplace might have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney crane (utilized in kitchen and laundry fireplaces), a grate, a lintel, a lintel pub, house overmantel, a damper, a smoke room, a throat, a flue, and a chimney filter or afterburner.

On the exterior there is often a corbeled brick crown, where the casting courses of brick function as a drip route to keep rainwater from running down the outside walls. A hood, cap, or shroud serves to keep rainwater out of the outside of the chimney; rain at the chimney is a much larger difficulty in chimneys lined with impervious flue tiles or metal liners than with the standard masonry chimney, that divides up all but the rain. Some chimneys have a spark arrestor integrated into the cap or crown.

Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by gel, liquid propane, bottled gas or natural gas. In the USA, some states and local counties have laws restricting these kinds of fireplaces. There are also air quality control issues because of the quantity of moisture they release in the room air, and oxygen detector and carbon dioxide sensors are security essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed in the place that is heated, and port all exhaust gasses to the outside of the structure.

Over time, the purpose of fireplaces has transformed from one of requirement to one of interest. Early ones were fire pits than contemporary fireplaces. They have been used for heat on chilly days and nights, in addition to for cooking. They also served as a gathering place inside the house. These fire pits were generally centered within a space, allowing more individuals to collect around it.

Many defects were found in ancient fireplace designs. Together with the Industrial Revolution, came large scale housing developments, requiring a standardization of fireplaces. The most renowned fireplace designers of this time were the Adam Brothers. They perfected a style of fireplace design which has been used for generations. It was smaller, more brightly lit, with a emphasis on the level of the substances used in their construction, instead of their size.
From the 1800s newest fireplaces were made up of 2 components, the surround as well as the insert. The surround consisted of the mantlepiece and sides supports, usually in wood, marble or granite. The fit was where the fire burnt, and was constructed of cast iron frequently backed with ornamental tiles. In addition to providing warmth, the fireplaces of the Victorian era were believed to add a cozy ambiance to homes.Kipling Ventless Gel Fuel Fireplace In White With Cast Logs, 54x42 Video
Some fireplace units incorporate a blower which transfers more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated space and a lower heating load. Fireplace efficiency is also enhanced with the use of a fireback, a sheet of metal that sits behind the fire and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but can also be manufactured from stainless steel. Efficiency is a complex concept although with open hearth fireplaces. Most efficiency tests consider just the effect of heating of the atmosphere. An open fireplace is not, and never was, intended to warm the atmosphere. The ideal way to estimate the output of a fireplace is in case you detect you are turning the thermostat up or down.
Most elderly fireplaces have a comparatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum necessity such as in Salzburg/Austria). To improve efficiency, fireplaces can also be modified by inserting special heavy fireboxes designed to burn much cleaner and may reach efficiencies as large as 80 percent in heating the air. These modified fireplaces are usually equipped with a massive fire window, allowing an efficient heating process in two stages. During the first stage the initial heat is provided through a large glass while the fire is burning. In this time period the structure, constructed of refractory bricks, absorbs the warmth. This warmth is then evenly radiated for several hours during the second phase. Masonry fireplaces with no glass fire window just provide heat radiated from the surface. Depending on outside temperatures 1 to 2 daily firings are enough to ensure a constant room temperature.ventless fireplace
